Cred ca ,,v'' e radical....
a) 588=a radical 3
a=588/radical 3 (rationalizezi cu radical 3)
a=(588 radical 3)/3 (simplifici 588 si 3 cu 3)
a=196 radical 3
b) radical 1875=25/a
descompui radical 1875 = 25 radical 3
25 radical 3=25/a (produs mez egal cu produs extrem)
25 radical 3 • a=25 /:25
radical 3 • a=1
a=1/radical 3 (rationalizezi cu radical 3)
a=radical 3/3
c si d mi se par incomplete, gen la c, a=7 radical 5, si la d a=8 radical 6 ??
